1343 still being worked on. Mark Elf configurations (except sparc and
1344 i386) as developmental. Deleted cases matching some generic names
1345 in favor of more specific names. (E.g., when we get Alpha

1363 for functions only used within tc-hppa.c, likewise for structures,
1364 variables, and #defines. Try to group OBJ_ELF and OBJ_SOM
1365 conditional code in a few small places.

1373 Add comments to functions. Delete unused functions, variables,
1374 #defines, etc. Delete unused members within structures. Delete
1375 ldil;ble hacks -- it is believed they were installed to work
1376 around old gas bugs. Avoid using mixed case for local
1377 functions, variables, and structures. Fix formatting problems
1378 not found by GNU-indent. Add FIXME notices for things which
1379 should be worked on the near future. Delete lots of old
1380 useless (1.36 PA-SOM) code.

2458 are also magic, and have special default flag settings.
2459 (obj_elf_frob_symbol): Since the return value from this function

2523 * Extensive changes to permit symbols to contain any expression
2524 type and to delay the computation of the expression until the
2525 value is actually needed. This permits setting symbols to values
2526 calculated based on object code size. Expressions were changed to
2527 no longer be in a section, to stop the overloading of segment and
2528 expression type that previously occurred.
2530 * as.c (big_section, pass1_section, diff_section, absent_section):
2532 (expr_section): Added (used for dummy symbols which hold

2616 (previous_section, previous_subsection): New vars.
2617 (obj_elf_section): Save current place in case DWARF code wants us
2618 to pop back to it. Handle unquoted section name as well as quoted
2619 section name. Don't crash on invalid strings.
2620 (obj_pseudo_table): Handle new pseudos "previous", "2byte", and

2732 sy_resolved and sy_resolving single bit fields.
2733 * symbols.c (symbol_new): Don't initialize sy_forward field.

3766 * as.h (const, volatile): Put these definitions back, and use
3769 * doc/as.texinfo: First pass at using new texinfo features --
3770 variables, conditional tests. Far from complete.

3798 dependencies are read, not when they are used).
3800 * config/obj-coffbfd.c (fill_section): Don't set NOLOAD bit for
3801 a29k .bss section; the mondfe program doesn't like it.

3850 avoid some redefinition complaints on some systems.
3851 (const, volatile): Don't need these conditionally defined if we
3852 use CONST and VOLATILE from ansidecl.h.
3853 (seg_name): Use CONST, not const.
3855 Fri Mar 26 10:22:04 1993 Ian Lance Taylor (ian@cygnus.com)
3857 * config/tc-mips.c: Reindented to GNU standards.

3861 * config/obj-coffbfd.c (do_relocs_for): Remove a29k special case.
3862 (fixup_segment): Add a29k special case; the linker is not prepared
3863 to see a segment offset here.
3865 * app.c (do_scrub_next_char): Added new state, 10, modifying state

3868 Wed Mar 24 02:16:22 1993 david d `zoo' zuhn (zoo at poseidon.cygnus.com)
3870 * Makefile.in: add dvi target; as-$(config).texinfo might live in

3886 bignums, but don't emit error message.
3888 Fri Mar 19 21:02:19 1993 Jim Wilson (wilson@sphagnum.cygnus.com)
3890 * Makefile.in (targ-cpu.o): Depend on config.h.
3892 Wed Mar 17 16:44:06 1993 Ian Lance Taylor (ian@cygnus.com)
3894 * app.c (do_scrub_next_char): Added new state, 9, to avoid
3895 dropping a space immediately following an identifier.
3896 * expr.c, write.c: Rewrote assert expressions to not use multiple
3897 lines; I don't think that can be done portably.
3898 * config/tc-mips.c (macro): Use $AT if target register is zero in
3899 load instruction, which it can be for a floating point load.
3901 Mon Mar 15 12:17:28 1993 Ian Lance Taylor (ian@cygnus.com)

3922 Fri Mar 12 12:00:07 1993 Ian Lance Taylor (ian@cygnus.com)
3924 * expr.c, write.c: Ultrix native 4.2 cc requires assert condition
3925 to be on a single line.
3927 Thu Mar 11 17:56:22 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

3973 prototypes for all static functions. Moved existing minimal
3974 debugging format support info #ifndef OBJ_ECOFF blocks.

4023 * make-gas.com: Find obstack.obj if it's not in the current
4025 * read.c (s_ignore): Don't declare is_end_of_line. It's
4026 redundant, and triggers a VMS gcc compiler bug.
4028 * write.c (write_object_file): Macro SUB_SEGMENT_ALIGN now takes
4029 current segment as an argument. (Ignored in all cases but VMS.)
4030 All callers and definitions changed.

4327 md_relax_table): Use default zero initialization.
4328 (s_reserve): Since SEG_E2 is equivalent to SEG_BSS, just use the
4329 latter, instead of selecting with preprocessor conditionals.
4331 Thu Jan 7 08:58:21 1993 david d `zoo' zuhn (zoo at cirdan.cygnus.com)
4333 * configure.in: recognise all sparclite variants
4335 Thu Jan 7 05:25:25 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)

4341 Tue Jan 5 08:42:16 1993 Ken Raeburn (raeburn@cambridge.cygnus.com)
4343 * expr.c (operand): If character other than comma or newline is a
4344 logical end-of-line character, use the newline case.
4345 From Eric Youngdale:
4346 (operand): Set X_add_number field for floating-point numbers.
4347 (operand): Treat zero byte as end-of-operand.
4349 * configure.in (per-target): Look for with_bfd_assembler option.
4350 For now, only accept "no", until the merge is done.
4352 Merged changes from Eric Youngdale (youngdale@v6550c.nrl.navy.mil):
4353 * as.c, flonum-konst.c, hex-value.c, input-file.c, version.c,
4354 config/obj-aout.h, config/obj-vms.c: VMS -> HO_VMS.
4355 * read.c: Finish conversion to S_* macros in the VMS only
4356 parts of the program. Add "const" modifier to hex_value.
4357 * as.c, read.c, symbols.c, write.c: Change "ifdef VMS" to
4359 * expr.c: Add "const" modifier to hex_value.
4360 * symbols.c: Finish conversion to S_* macros in the VMS only
4361 parts of the program. Add "const" modifier to
4362 md_[long,short]_jump_size. Remove declaration of const_flag
4363 (which will be declared in obj-vms.h).
4364 * write.c: Add "const" modifier to md_[long,short]_jump_size.
4365 Fix arguments to VMS_write_object_file.
4366 * config-gas.com: New file. Script for VMS systems to set up the
4367 configuration to build gas for VMS, and create config.status.
4368 * make-gas.com: Redone to work with new scheme.
4369 * obj-vms.c: Patch to fix bug where we were not correctly parsing the
4371 * obj-vms.c: Define macros COPY_LONG and COPY_SHORT which
4372 will swap bytes if needed on a big endian system. Use throughout
4374 * obj-vms.c (obj_aout_stab): Add code to generate listing file.
4375 * obj-vms.c (VMS_typedef_parse): Add alias to correctly handle certain
4376 types of malformed stabs. Change parsing algorithm so that we are
4377 more certain of having all of the information that we need on hand.
4378 * obj-vms.c (final_forward_reference): New function, used to help
4379 resolve the data types of as many struct elements as possible
4380 when some part of the struct is not fully defined by the compiler.
4381 * obj-vms.c (VMS_LSYM_Parse): Correctly handle case of continuation
4383 * obj-vms.c (VMS_write_object_file): Define all vtable psects
4384 as symbols as well in the object file. Look for external functions
4385 that start with "__vt.", and turn them into variables, since the
4386 g++ compiler is incapable of doing this.
4387 * tc-vax.c: Add '1' option for backward compatibility with older GCC
4389 * bignum-copy.c (bignum_copy): Fix bug where we pad with zeroes.
4390 * input-scrub.c (as_where): Fix bug where as would crash if we did not
4391 have the name of the source file yet.
4392 * config/ho-vms.h: define HO_VMS, not HO_VAX.
4394 Mon Jan 4 05:17:26 1993 Ken Raeburn (raeburn@cygnus.com)
4396 * read.c (s_data): Always use "data_section", since it'll map to
4397 SEG_DATA or SEG_E1 if needed.
4398 (s_lcomm): Likewise with bss_section.
4399 (s_fill): Use memset, not bzero.
4401 Thu Dec 31 04:29:27 1992 Ken Raeburn (raeburn@kr-pc.cygnus.com)

4422 (section_alignment): Declare only if not BFD_ASSEMBLER.
4423 (big_section, reg_section, pass1_section, diff_section,
4424 absent_section, text_section, data_section, bss_section): If
4425 BFD_ASSEMBLER, declare as variables; otherwise, declare as macros,
4426 mapping to segT enum values.
4427 (tc_aout_fix_to_chars, next_object_file_charP): Force parse errors
4428 if these are used or defined, if BFD_ASSEMBLER.
4429 (subseg_set, subseg_new) [BFD_ASSEMBLER]: Functionality of old
4430 subseg_new split into two functions.
4431 (SEG_NORMAL): For BFD_ASSEMBLER, always return true, for now.
4433 * as.h (volatile): Don't define if already defined.
4434 (had_errors, had_warnings): Provide prototypes for ANSI C even if
4436 (as_bad, as_fatal, as_tsktsk, as_warn): For GNU C version 2,
4437 declare with format attribute for -Wformat checking.
4439 Wed Dec 30 10:18:57 1992 Ian Lance Taylor (ian@cygnus.com)
4441 * app.c, config/tc-*.c: Don't include read.h, since it is already
4444 * These are based on patches from Minh Tran-le
4445 <mtranle@paris.intellicorp.com>.
4446 * configure.in (i[34]86-ibm-aix*): Accept i486 for host. Use
4447 obj_format coffbfd and gas_target i386coff for target.
4448 (i[34]86-*-isc*): New host (uses sysv).
4449 * config/i386aix.mt: Removed (no longer used).
4450 * config/mh-i386aix (RANLIB): Use true rather than /bin/true.
4452 (LDFLAGS): Added, defined as -shlib.
4453 * config/te-i386aix.h (REVERSE_SORT_RELOCS): Undefine.
4454 * config/te-sco386.h (LOCAL_LABEL): Don't define.
4455 (DOT_LABEL_PREFIX): Define.
4456 * expr.c (operand): If DOT_LABEL_PREFIX, use .L0\001 as a label
4457 name rather than L0\001.
4458 * read.c (s_lcomm): Make a frag in SEG_BSS rather than using
4460 * symbols.c, symbols.h (local_bss_counter): Removed.
4461 * write.c (write_object_file): bss no longer uses
4462 local_bss_counter. Pass correct data and bss size to
4463 VMS_write_object_file.

4469 (size_section): Restored sanity check.
4470 (do_relocs_for): Base section address on s_paddr rather than
4471 computing it. Adjust a29k R_IHIHALF special case to account for
4472 section paddr (used to require paddr to be zero). If there are no
4473 reclos, set s_relptr to 0. Set relocation size in object_headers.
4474 (fill_section): Always set s_vaddr here, removing
4475 ZERO_BASED_SEGMENTS case. Force s_scnptr for bss to 0. Don't set
4476 NOLOAD for i386 .bss, because it confuses the SVR3 native linker.
4477 Set STYP_INFO for .comment.
4478 (coff_header_append): Use object headers and H_{SET,GET}_* macros.
4479 Make aouthdr writing depend on OBJ_COFF_OMIT_OPTIONAL_HEADER.

4481 H_{SET,GET}_* macros.
4482 (do_linenos_for): Set lineno size in object_headers.
4483 (write_object_file): Use H_{SET,GET}_* macros. Don't bother to
4484 set s_vaddr here. If string_byte_count remains 4, set it back to
4485 0, and only write strings out if there are some. Call
4486 fill_section before do_relocs_for and do_linenos_for.
4487 (obj_coff_section): Handle optional quoted second argument giving
4488 section characteristics.
4489 (obj_coff_bss): Added to handle .bss.
4490 (obj_coff_ident): Added to handle .ident (puts string in .comment

4493 (fixup_mdeps): Change to segment. Call frag_wane after
4495 (fixup_segment): Explicitly check S_IS_COMMON before making 386
4496 adjustment (already happened only for common symbols, but this is
4498 * config/obj-coffbfd.h (OBJ_COFF_OMIT_OPTIONAL_HEADER): Define.
4499 * config/tc-i386.c (s_bss): Don't use if I386COFF.

4510 (do_scrub_next_char): For \", return " not '.
4511 (symbol_chars): Now const.
4513 * expr.c (operand): If not LOCAL_LABELS_FB, don't look for "0f"
4514 and "0b". If LOCAL_LABELS_DOLLAR, check for "0$".
4516 * config/obj-coff.h: Don't use #elif.
4518 * config/ho-sunos.h: Don't include sys/stdtypes.h; 4.0.3 doesn't
4519 have it. (Reported by Noah Friedman, friedman@gnu.ai.mit.edu.)
4521 Wed Dec 16 12:12:33 1992 Ian Lance Taylor (ian@cygnus.com)
4523 * write.c, obj-ieee.c: don't define SUB_SEGMENT_ALIGN if it is

4545 * config/obj-coffbfd.c (do_relocs_for): Increment addr even if not
4546 using ZERO_BASED_SEGMENTS.
4547 (fill_section): If ZERO_BASED_SEGMENTS, set segment addresses, but
4548 never set segment address for SEG_E2 (.bss) and don't write out
4549 SEG_E2 contents. Set .init and .fini sections to STYP_TEXT.
4550 (obj_coff_endef): Don't merge labels or symbols awaiting forward
4551 definitions, and don't merge tags with non-tags. Check for .bf
4552 rather than just checking whether the second character is b and
4553 the third character is f.
4554 (obj_coff_val): gcc can generate values which we don't handle
4555 correctly; discard information for now, since it only affects the
4556 debugging information.
4557 (tag_find_or_name): Don't insert tags in the symbol table.
4558 (yank_symbols): Don't merge labels.
4559 (write_object_file): Don't define SUB_SEGMENT_ALIGN if it is

4737 consistently const, and always initialized them. Included read.h.
4739 Thu Nov 5 17:55:41 1992 Jim Wilson (wilson@sphagnum.cygnus.com)
4741 * tc-sparc.c (sparc_ip): Add code to flag error if an absolute
4742 constant will not fit in an immediate field.
4743 (md_apply_fix, RELOC_BASE13 case): Check for relocation overflow.
4745 Wed Nov 4 07:50:46 1992 Ken Raeburn (raeburn@cygnus.com)
4747 * obj-coff.c (callj_table): Delete global variable.

4762 * tc-i960.h (N_BALNAME, N_CALLNAME): Define as char-type values,
4763 so widening works consistently.
4765 Wed Oct 28 08:52:34 1992 Ken Raeburn (raeburn@cygnus.com)
4767 * version.c: Put conditional "const" before version_string, not
4768 before dummy function for VMS. Now version 1.91.03.
4770 * app.c (do_scrub_next_char): Need double-\ before `000' to show
4771 printed rep of null character.
4773 Fri Oct 23 14:40:38 1992 Ian Lance Taylor (ian@cygnus.com)
4775 * obj-coffbfd.c (write_object_file): check return value of
4778 Tue Oct 20 12:18:08 1992 Ian Lance Taylor (ian@cygnus.com)
4780 * Support for i386-sysv.
4781 obj-coffbfd.c (do_relocs_for, write_object_file): set segment
4782 addresses to reasonable sizes. New define ZERO_BASED_SEGMENTS can
4783 be used to set them all to zero as was done before.
4784 (fill_section): segment addresses now set in write_object_file.
4785 (fill_section): Don't set STYP_NOLOAD for .bss section.
4786 (fixup_segment): 386 uses strange common symbol format.
4787 tc-i386.c (tc_coff_fix2rtype): use R_DIR32, not R_RELLONG, for
4788 compatibility with SVR3.2 linker.
4789 * configure.in: i386-sysv and i386-sco use coffbfd.

4801 * obj-coff.c (c_dot_file_symbol, obj_coff_ln, obj_coff_line):
4802 support for C source listings. (obj_coff_endef): look in the right
4803 part of the symbol for the symbol name
4805 * tc-m68k.c (get_num): make it work for all segments, not just the
4808 Mon Oct 5 03:30:36 1992 Mark Eichin (eichin at tweedledumber.cygnus.com)

4819 * tc-z8k.c: lots of bug fixes
4821 Tue Sep 29 10:51:55 1992 Ian Lance Taylor (ian@cygnus.com)
4823 * tc-i960.h, tc-i960.c: avoid the ANSI preprocessor addition
4824 #elif, since it is not supported by old compilers.
4825 ho-rs6000.h, tc-m68k.c: the native RS/6000 compiler miscompiles a
4826 couple of expressions in tc-m68k.c.
4828 Mon Sep 28 21:18:24 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4830 * read.c (cons): If NO_RELOC is defined, use it.
4832 * tc-i960.c (get_cdisp): Use NO_RELOC, not 0, in call to fix_new.
4834 Fri Sep 25 18:18:52 1992 Ian Lance Taylor (ian@cygnus.com)
4836 * tc-m68k.h: if M68KCOFF, define DOT_LABEL_PREFIX (to require
4837 local labels to start with a .) and set REGISTER_PREFIX to %.
4838 tc-m68k.c (m68k_reg_parse): accept REGISTER_PREFIX if defined.

4856 * obj-coffbfd.c (do_relocs_for,fill_section): now allocate all
4857 sections starting from zero, rather than making them consecutive.
4858 This makes subsequent reloc calculations easier, esp if the object
4859 format doesn't understand addends. (obj_coff_lcomm): (maybe temporarily)
4860 allocate lcomm in .data rather than in .bss. It seems that some
4861 tools can't cope with a non-zero sized bss before linkage.
4863 Tue Sep 22 15:10:51 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4865 * tc-m68k.c: Replace "enum m68k_architecture" with "int"
4866 throughout. That enum no longer means what we thought it meant.

4884 * Makefile.in (install): if $(tooldir) exists, install as in
4887 Sun Sep 13 20:30:10 1992 Ian Lance Taylor (ian@cygnus.com)
4889 * Added WARN_SIGNED_OVERFLOW_WORD define to give an error if any
4890 .word is < -32768 or > 32767. The -J flag causes the error to be
4891 ignored. This is to catch over-sized switches generated by gcc on
4892 systems which don't support the broken .word hack.
4893 as.c (main): permit -J if WARN_SIGNED_OVERFLOW_WORD.
4894 write.c (fixup_segment): check for signed .word overflow if
4895 WARN_SIGNED_OVERFLOW_WORD.
4897 * write.c (fixup_segment): fixed missing parens in expression
4898 checking for byte or word overflow.

4914 Thu Sep 10 09:23:15 1992 Ian Lance Taylor (ian@cygnus.com)
4916 * input-scrub.c (input_scrub_push): call input_file_begin, not
4918 messages.c (as_perror): print ": " between the passed in error and
4919 the strerror, like perror does.
4921 Wed Sep 9 11:06:25 1992 Ian Lance Taylor (ian@cygnus.com)

4924 From Steve Chamberlain:
4925 Makefile.in: Handle m68*-*-coff*.
4926 read.c, read.h: add mult argument to s_space
4928 * tc-m68k.c (m68k_ip, m68k_ip_op, get_num, try_moto_index): merge
4929 Motorola and MIT syntax; gas can now assemble either type of
4931 tc-m68kmote.c, tc-m68kmote.h: removed now superfluous files.

4938 (fixup_segment) set fx_subsy to 0.
4939 obj-coffbfd.h: define WORKING_DOT_WORD (too hard to support) and
4941 tc-m68k.c, config/tc-m68k.h: added m68k COFF support and Motorala
4944 Tue Sep 8 17:10:58 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4946 * Makefile.in (LIBS): Include opcode library.

4971 Tue Aug 25 15:50:48 1992 Ken Raeburn (raeburn@cambridge.cygnus.com)
4973 * config/tc-m68k.c (init_table): Now const. Always include 68851
4974 data, so that "bc" is available to 68040 cache instructions.
4975 Added "tt0", "tt1", and 68ec030 variants.
4976 (md_assemble): Complain if 68000 (only) and 68881 are specified.
4977 (enum _register): Added TT0, TT1.
4978 (m68k_ip, cases '3' and 't'): Handle new operand type codes. Pass
4979 line number correctly in "internal error" messages. Don't print
4980 architecture-mismatch message for operand errors.
4982 From Colin Smith (colin@wrs.com):
4983 * config/tc-m68k.c (m68k_ip, case '_'): Use addword twice rather
4984 than install_operand.

5005 * messages.c (as_warn): Use fputs, not fprintf, with a buffer that
5006 has already been formatted (but may still contain %-characters).
5009 Wed Aug 19 11:20:59 1992 Ian Lance Taylor (ian@cygnus.com)
5011 * tc-m68k.c, tc-m68kmote.c: the cas2 instruction is supposed to be
5012 written with indirection on the last two operands, which can be
5013 either data or address registers. Added a new operand type 'r'
5014 which accepts either register type. Added '(' to notend stuff in
5015 tc-m68kmote.c to accept (a0):(a2) in cas2 instruction.

5034 their not having symbols associated.
5036 * tc-i960.c (norelax, instrument_branches): Default initializer is

5062 being used with args swapped, causing occasional lossage when
5063 refilling buffers after an include file.

5121 * expr.c (floating_constant): Separate "=-" to avoid confusing
5122 ancient or broken compilers.
5124 * config/tc-m68k.c (m68k_ip): Mismatch error could also indicate
5125 processor/opcode mismatch, so reword the error message.
5126 (md_assemble): If no CPU has been set (even if FPU/PMMU
5127 characteristics have been), default to 68020. Don't need extra
5128 quotes around error string.

5205 subsegment with a value which might interfere with out -R hackery.
5206 * config/tc-m68k.c (m68k_reg_parse): lookup names in symbol table
5207 rather than use ugly if tree. (init_regtable): insert register
5208 names into symbol table.
5210 Tue Jun 2 16:47:09 1992 Steve Chamberlain (sac@cygnus.com)
5212 * write.c (write_object_file): keep the fix_tail clean, which
5213 fixes a bug in -R where relocations were being lost.
5215 Mon Jun 1 16:20:22 1992 Michael Tiemann (tiemann@cygnus.com)
5217 * configure.in: recognize m680x0 as having sun3 emulation mode for
5218 vxworks environment.

5240 Mon May 4 18:56:19 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5242 * obj-coffbfd.c: use is a synonym for section, (do_relocs_for):
5243 calc the base of relocs correctly.
5244 * tc-a29k.c (parse_operand): allow expressions to be in any section.
5246 Mon Apr 27 13:13:31 1992 K. Richard Pixley (rich@cygnus.com)
5248 * as.c, write.c: use -K rather than -k for the broken word warning
5251 Tue Apr 21 13:35:30 1992 K. Richard Pixley (rich@cygnus.com)
5253 * Makefile.in: do not print recursion lines.
5255 Wed Apr 15 21:19:31 1992 K. Richard Pixley (rich@rtl.cygnus.com)

5259 Tue Apr 14 14:50:22 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5261 * write.c (write_object_file): For b.out format, round up section
5262 start addresses to match required alignment.
5264 Thu Apr 9 05:45:29 1992 Ken Raeburn (Raeburn@Cygnus.COM)
5266 * Makefile.in (install): Install into $(tooldir)/bin, since that's
5267 where gcc looks for it.
5269 Tue Apr 7 15:12:15 1992 Sean Eric Fagan (sef@cygnus.com)
5271 * Makefile.in: Changed some lines to be less confusing for some
5274 * input-file.c: Conditionalize on _IOFBF, not VMS.
5276 * read.c, write.c: Change a series of ifdef/elif to
5277 ifdef/else/ifdef etc.

5291 Fri Mar 13 08:03:03 1992 Steve Chamberlain (sac@thepub.cygnus.com)
5293 * flonum-const.c: renamed flonum-konst.c to stop dos name
5296 Thu Mar 12 04:42:38 1992 K. Richard Pixley (rich@cygnus.com)
5298 * tc-m68k.h, te-sun3.h: moved LOCAL_LABELS_FB definition from
5299 tc-m68k.h to te-sun3.h.
5301 Wed Mar 11 23:32:42 1992 K. Richard Pixley (rich@cygnus.com)
5303 * configure.in: vxworks68 gets te-sun3.h.
5305 * expr.c: remove limitation that local_labels_dollar or
5306 local_labels_fb must be < 10.
5308 * symbols.c: remove local_labels_dollar, replace with a function
5309 interface for a sparse array. All users adjusted.
5311 * te-sun3.h: add LOCAL_LABELS_DOLLAR.
5313 Sat Mar 7 00:06:25 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5315 * doc/Makefile.in: commented out line for building as-all.texinfo.
5318 * doc/as.texinfo, doc/as-all.texinfo: added menu item hooks.
5320 Fri Mar 6 21:57:18 1992 K. Richard Pixley (rich@cygnus.com)

5332 Sat Feb 29 13:59:10 1992 Michael Tiemann (tiemann@cygnus.com)
5334 * Makefile.in (strerror.o): Add rule so that broken Sun make can
5337 Wed Feb 26 19:26:28 1992 Steve Chamberlain (sac at thepub.cygnus.com)
5339 * read.c, obj-coffbfd.c : fix h8300 specific bit rot
5341 * expr.c (operand): if can't work out what sort of operand it is,
5342 then look through FLT_CHARS for a hint.
5344 Wed Feb 26 18:04:40 1992 K. Richard Pixley (rich@cygnus.com)
5346 * Makefile.in, configure.in: removed traces of namesubdir,
5347 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5348 copyrights to '92, changed some from Cygnus to FSF.
5350 * doc/Makefile.in, doc/configure.in: removed traces of namesubdir,
5351 -subdirs, $(subdir), $(unsubdir), some rcs triggers. Forced
5352 copyrights to '92, changed some from Cygnus to FSF.
5354 Tue Feb 25 14:17:15 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5356 * expr.c: If an expression is single comma, then return with
5357 SEG_ABSENT rather than an error - since the sparc front end does
5358 really strange things with things like fbge,a
5360 * as.h: include bfd.h if using many sections
5361 * expr.c: LOCAL_LABELS_FB had been changed to lower case - so
5362 local labels didn't work.
5363 * listing.c (list_symbol_table): don't core dump when there's no
5365 * write.c, write.h: call fix_new with the right number of args on
5367 * config/tc-h8300.[ch] : fix bugs reported by HMSI, and make
5370 Sat Feb 22 12:26:28 1992 Steve Chamberlain (sac at rtl.cygnus.com)
5372 * app.c: MRI compatibility - allow single quote to start a string.
5373 * as.c: fix typo recently introduced.
5374 * as.h : Don't include aout/reloc.h - it's not right for COFF!
5375 * expr.c: Much rewriting, to accomodate MRI syntax for
5376 expressions. Also easier to read now.
5377 * listing.c: Put back defuns
5378 * read.c: modified to accept MRI syntax, put back listing pseudo
5379 ops so that an assembler built with NO_LISTING ignores list ops
5381 * write.c, write.h: fixs - only keep a reloc type in a fix if the target
5382 machine is a SPARC or a 29K.
5383 * config/obj-aout.c: added s_sect pseudo op
5384 * config/obj-coffbfd.c: lints, set the filehdr flags right and
5385 fill in the timestamp.
5386 * config/obj-coffbfd.h: Since we don't include aout/reloc.h
5387 anymore, define all the relocs which the tc-<x> bit will use so we
5388 can translate from them to the coff types.
5389 * config/tc-a29k.c: reloc_type isn't ane enum any more
5390 * config/tc-m68k.c: Added NO_RELOC definition.
5392 Fri Feb 21 06:21:07 1992 K. Richard Pixley (rich@rtl.cygnus.com)
5394 * Makefile.in: put header files before C source for TAGS; remove
5395 references to non-existent syscalls.h.
5397 * read.c, write.c subsegs.c: back out the .bss changes.
5399 * obj-aout.c: do not include stab.gnu.h if NO_LISTING.
5401 * tc-i860.c, a.out.gnu.h: move i860 relocs to a proper place.
5405 Fri Feb 21 01:08:48 1992 Minh Tran-Le (TRANLE@INTELLICORP.COM)
5407 * symbols.c (local_label_name): symbols now start with ^A.
5409 * read.c, subsegs.c, write.c obj-coff.c: added handling of
5410 `.bss` pseudo op for unitialized data. The new gcc (1.37.9x)
5411 generate these sections. .align: will use NOP_OPCODE or 0
5412 for padding. This is just for being nice to the
5415 * expr.c (operand): changed to generate local label "\001L0"
5416 starting with a ^A so that it is recognized as a local label.
5418 * as.c (perform_an_assembly_pass): zero bss_fix_root, too.
5420 * tc-i386.c: tc-i386.c: added handling of the following opcodes:
5421 i/o opcodes - inb, inw, outb and outw. string manipulation with
5422 att syntax - scmp, slod, smov, ssca, ssto.
5424 * obj-coff.c: (for aix386) Moved the symbols .text, .data and .bss
5425 to just after .file .
5427 In obj_crawl_symbol_chain() where it tries to put the external
5428 symbols apart, with the condition:
5429 (!S_IS_DEFINED(symbolP) &&
5430 !S_IS_DEBUG(symbolP) &&
5431 !SF_GET_STATICS(symbolP))
5432 it was moving too many symbols out. So I switch it back to the
5434 (S_GET_STORAGE_CLASS(symbolP) == C_EXT && !SF_GET_FUNCTION(symbolP))
5436 In obj_emit_relocations() added the conditional on KEEP_RELOC_INFO
5437 so that we don't use the F_RELFLG which make the linker complain
5438 that somebody has stripped the relocation info.
5440 Also, the AIX ld program require that the relocation table
5441 is sorted by r_vaddr like the standard ATT assembler does.
5443 [he also changed the sizeof(struct ...)'s into the coff
5444 style FOOSZ macros. I'm not sure this is right, but I can't
5445 remember why. xoxorich.]
5447 Fri Feb 21 01:08:48 1992 K. Richard Pixley (rich@cygnus.com)
5449 * Makefile.in, configure.in, doc: use the doc. Build it, install
5452 Tue Feb 18 02:21:25 1992 K. Richard Pixley (rich at cygnus.com)
5454 * read.c: white space and comments only.
5456 * configure.in: use the new atof-ns32.c for ns32k.
5458 * write.c: comment change only.
5460 * tc-m88k.[hc]: pulled in from hack's unfinished work. These
5461 aren't yet integrated.
5463 * tc-i860.[hc]: blew off the dust. Something must still be done
5464 about conflicting relocation types.
5466 * tc-ns32k.c: Replaced previous tc_aout_fix_to_chars stub with the
5469 * tc-i960.c, tc-sparc.c: white space and comments only.
5471 * tc-a29k.h: delete duplicate macro definition.
5473 * new file atof-ns32k.c copied from hack's last unreleased gas.
5475 Mon Feb 17 07:51:06 1992 K. Richard Pixley (rich at cygnus.com)
5477 * config/tc-ns32k.c: actually make tc_aout_fix_to_chars work
5480 * nearly everything. flush ChangeLog, package as gas-1.92.1.
5481 ChangeLog's prior to this are sketchy at best. I have logs.
5482 They just aren't ChangeLogs.
